In its early stages, Alzheimers is virtually impossible to distinguish from other conditions that cause dementia.
Now researchers say they've discovered an enzyme that reacts abnormally in the skin of Alzheimers' victims.
It could lead to a quick and easy skin test capable of accurately diagnosing Alzheimers disease, even before symptoms occur.
Doctors say this test is important because treating the disease earlier could help patients live longer and more productive lives.
